Re: timing chain Defintely cheap insurance, but even a new one can break but it is less likely. My recommendation would be to go with a double roller for even more piece of mind.

Re: timing chain Get a double roller just in case. I'd hate to be in the middle of a race @ 6500 rpms and have your timing chain break. Then to have to take everything apart, replace the chain and anything else you broke in the process. When I took out my stock chain at 40K miles, it had some slack in it. I'm glad I got a double roller.

Re: timing chain
I reused my stocker as well as the oil pump...no problems yet and hopefully wont have any.
With just under 28k on it, seen no reason.

Re: timing chain I would be really pissed if I replaced my chain and gears and then the chain broke like Wicked's did, but things do happen. All we can do is minimize the risk of breakage by replacing critical items with new or better ones, but nothing is 100%.
For those still running a stock shain, why would you spend good money on a cam or heads/cam and not replace an $80 part. If you look at the stock setup against an aftermarket set like the RollMaster, the difference is amazing.

Re: timing chain Well, maybe thats why I didnt replace mine...never seen the difference with my eyes and hands between them. My stock chain seemed to be almost new, and guess I am just willing to risk it for a while. I dont plan on keeping this cam in so thought about swapping chain next cam. I will not replace the oil pump though. Heres why:
1) percentage of people that have had to redo the pumps, faulty porting etc..
2) percentage of people that have had to pull it all back apart for a damn little o-ring, **** porr design on that one
3) there is no significant increase in pressure or volume unless the stock pump is out of tolerance.
Matter of fact my friend had a H/C plus new chain and pump installed buot same time as i did mine. he ran his car less than 1,000 miles since (i have over 4,000) and his oil pump is not flowing oil anymore, used to be up at 60+psi, not anymore. Too much already.
But agreed to lose the chain on our valvetrain will suck, so new one will go in shortly. What sup with the doubles and clearing the ASP pulleys? Is this fixed or not? Have a newer (SFI spec'd) pulley will the double clear or do i need to "custom machine"?
